This invention relates to electrical connectors adaptable as circuit breakers. l

This invention has utility when incorporated in pronged electrical attachment devices with readily replaceable electric fuses.

Referring to the drawing: Fig. 1 is a side elevation of an embodiment of the invention as an intermediate connecten, Fig. 2 is a view from the right of Fig. 1, showing the prong seats for a complementary connector;

Fig. 3 is a view of the device of Fig. 1 :from the left, showing the-,prongs in elevation;

Fig. 4 is a view similar to Fig. 3 with the insulator disk removed to show the terminals, clips,

and fuse;

Fig. 5 is a section on the line V-V, Fig. 4, showing relation of the terminals in the conhector;

Fig. 6 is a view in elevation from the left of Fig. 5, with the insulation shell removed, thereby 1 leaving the terminals;

' Fig. 7 is a showing oi the connector as a direct attachment instead of intermediate;

Fig. 8 is a view looking into the connector of Fig. '1 from the prong side with the insulation diskremoved showing the electric terminals; Fig. 9 is a bottom plan view of a ilat type oi connector without insulation closure plate; and

3i) Fig. 1i) is a partial section on the line X--X, Fig. 9, showing the terminal prongs as adjacent the inse.

Insulation shell I (Fig. 5) say of molded plastic, has chamber portion 2, through 'openings 3 therefrom to prong intake seats 4. Screw ii is Y shown as anchoring prong 6 with complementary yieldable contact 'i in a prong seat. Companion to this screw 5 is screw 8 having integral with the shell l insulation collar 9 spacing yieldable contact Il) from this screw 8 and further positioned by insulation washer II held in position by clip strip I2 having companion prong I3 to the prong 6. This strip I2 has spring arch clip portion It. The yieldable contact II) has therefrom' yleldable w clip i5. These clips I4, I5, are in alignment with each other and with ports IS through the shell I in the vicinity ofthe chamber portion 2. insert-s able in a port I6 is fuse I1 having insulation ilat ends i8. For fuse replacement, a succeeding fuse is merely thrust through to expel the defective fuse trom one port It as the replacement fuse enters the companion or opposite port IB. With this fuse set-up edected, insulation disk I9 with ports 2li for the respective prongs 6. I3, com- (Cl. 20o-115.5)

pletes theassembly for this electrical connector or attachment.

In lieu of an intermediate prong iixture, this connector may directly receive electric conductors 2| (Figs. 7, 8) as supply lines in cord 22. OneV l of these conductors 2| may connect to terminal screw 23 and the companion conductor 2| to terminal screw 24. The screw 23 is connected to prong 25. The screw 24 is connected to clip 26 for the fuse Il as a conductor to companion clip l* 21, anchored with shell 28 by screw 29 and mounting companion prong 30. The screws 5, 8, anchor the prongsi, I3, with the shell I andthe terminal screws 23, 24, supplement the screw 29 in .assembly with the shell 2s of these electric conductor elements. In this shell 28 ports or notches 3i are in alignment clear of insulation disk '32 so that replacement fuse -I1 may be inserted readily as a fuse I1 becomes defective.

In this set-up herein disclosed, there is indi-v vidual protection for the independent equipment, say whether it be electric lamp, sweeper, washing machine, or other household or power operated equipment. This individual fusing is of advantage in localizing the circuit breaking cut- 35 out to where the trouble has arisen and thus leaves the rest oi the equipment in power and undisturbed thereby. The one giving attention to the electrical apparatus is thus guided to the particular place of dlicuity by the inoperative 30 appartus and the cure for the circuit is readily effected by thrusting a replacementQ fuse as an extruding means for the defective fuse. This may be achieved independently of even pulling out the connector prongs. However, should one de- 'u sire to inspect, it is of course in order to pull out the connector and remove the insulation disk.7 thereby disclosing the visible intermediate section of the inse i1 as to whether or not such be intact. With the Ifuse terminals I8 as insulation n there is peripheral shielding for the connector Y notwithstanding the ports therefrom.

In lieu of the cylindrical type ci shell I (Fig. l) and the circular type of shell 28 (Fig. 7) there u 'may be adopted in the connector at type of Shell 33 (Figs. 9, lil). This shell 33 has port or opening 34 in which may be inserted cord 22 for supply lines 2i. A line 2l is directly connected to screw terminal Zit, fixed directly with prong u terminal t. The companion supply wire 2l extendsf to screw terminal 31 having direct connection to terminal clip 38 `in which may be inserted fuse I1, the remote end of whichA is embraced by companion terminal clip 39 havingr s necting with terminal Il.. said seats and way providing a socket for a terminals 4|, protrude replaceable fuse,
